Thanks dain, that was helpful.
I installed the javaagent and the openejb context loads at tomcat startup
prior to anything else.
Now my context discovered in the webapps loads at the correct time.
I still have a problem when I explicitely set a new context in the
server.xml...
OpenEJB loads first, but when MyWebApp loads, the following exception arises
:
ERROR - Unable to load web.xml in war testMain: Exception: Cannot read the
web.xml file: jndi:/localhost/testMain/WEB-INF/web.xml: null

Strange, isn't it ?
The rest of the ejb-jars loads correctly, but I have a problem then in a
servlet :

The message of the exception could be translated in plain ol' english as
follow :
ERROR: Error while configuring the application listener LaunchTest
javax.naming.NameNotFoundException: The Name LaunchTest isn't bound to any
context
Here is the source for the listener, which by the way works just fine
without declaring the context in the servlet.xml :
import javax.ejb.EJB;
import javax.naming.NamingException;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import test.beans.TestBean;
public class LaunchTest implements ServletContextListener {
@EJB
private TestBean bean;
public void contextDestroyed(ServletContextEvent arg0) {
}
public void contextInitialized(ServletContextEvent arg0) {
try {
System.out.println("/***************************************/");
System.out.println("/* run
*/");
System.out.println("/***************************************/");
bean.run();
} catch (NamingException e) {
throw new RuntimeException(e);
}
}
}
The context in the servlet.xml is declared as follow:
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
<Context docBase="../../target/CCV-Core-TestMain-0.0.1-SNAPSHOT"
path="testMain"/>
</Host>
CCV-Core-TestMain-0.0.1-SNAPSHOT is the real name for MyWebApp...
Anyway, thanks a lot for your help.
I greatly appreciate the responsiveness of the OpenEJB crew.
Cheers,
Juan Manuel
